I know there is some mechanism in humans by which we start to ignore a certain stimuli if it persists for a long time (e.g., we don't feel our shoes all the time !).
Can the same thing happen in Mimosa pudica? Can it again get it's original arrangement of leaves if it is stimulated without interruption?
I think it should do this, otherwise it will not be able to grow if it is surrounded by bushes from all the sides as it will be stimulated constantly and so will be unable to photosynthesize properly.
